#2 is SB or 6 cyl with air wp pulley.
#3 is a single groove 71- 72 V 8 van pulley

your PS pulley is from a 72 truck with a 6cyl.
Dont know what #1 is.

Thanks Rod!!! Yeah number one is throwing me off. The bolt hole spacings are smaller than the rest. It did come off a big block. But not sure why the spacings are different. Here is a couple of pics.
